zPages extension 🔗
The zPages extension serves zPages, an HTTP endpoint that provides live data for debugging different components, if they were properly instrumented for such. zPages are useful for in-process diagnostics without having to depend on any backend to examine traces or metrics.
All core exporters and receivers provide some zPage instrumentation.
Get started 🔗
This component is included in the default configuration of the Splunk Distribution of the OpenTelemetry Collector when deploying in host monitoring (agent) mode. See Collector deployment modes for more information.
For details about the default configuration, see Configure the Collector for Kubernetes with Helm, Collector for Linux default configuration, or Collector for Windows default configuration. You can customize your configuration any time as explained in this document.
Follow these steps to configure and activate the component:
Deploy the Splunk Distribution of OpenTelemetry Collector to your host or container platform:
Configure the extension as described in this doc.
Restart the Collector.
Sample configuration 🔗
This is a configuration example for the extension:
To complete the configuration, include the extension in the
service section of your configuration file:
The following settings are required to configure the extension:
endpoint. Specifies the HTTP endpoint that serves zPages.
localhost:to make the ZPages extension available only locally.
":"to make the ZPages extension available on all network interfaces.
See the full list of exposed settings in the section Settings.
Exposed zPages routes 🔗
The Collector exposes the following zPage routes:
ServiceZ gives an overview of the Collector services, and provides quick access to the pipelinez, extensionz, and featurez zPages. The page also provides build and runtime information.
For example, http://localhost:55679/debug/servicez .
PipelineZ brings insight on the active pipelines running in the Collector. You can find information on type, whether data is mutated, and the receivers, processors and exporters that are used for each pipeline.
For example, http://localhost:55679/debug/pipelinez .
ExtensionZ shows the extensions that are active in the Collector.
For example, http://localhost:55679/debug/extensionz .
FeatureZ lists the feature gates available along with their current status and description.
For example, http://localhost:55679/debug/featurez .
The TraceZ route examines and sorts spans by latency buckets like 0us, 10us, 100us, 1ms, 10ms, 100ms, 1s, 10s, or 1m. They also allow you to quickly examine error samples.
For example, http://localhost:55679/debug/tracez .
The Rpcz route helps examine statistics of remote procedure calls (RPCs) that are properly instrumented, such as gRPC.
For example, http://localhost:55679/debug/rpcz .
The following table shows the configuration options for the zPages extension:
